Not really sure which section this belongs in, not Apache, since this is firewall related, not search engine spiders since I already know what I want to block.
Anyway, here's the problem:
Like many others, my servers get hit on daily basis with a huge number of abusive requests from Amazon AWS ranges. I want to block these at the firewall level, and I have the IP ranges to do so. The issue is I use a couple of advertising services such as VigLink and GumGum which come through Amazon IPs. These have a few dozen IPs.
So, I'm looking for a tool or script which I can enter the IP ranges I want to block, but it rewrites them into smaller pieces so they are written "around" the IPs I want to allow in. I've searched Google to no available, and writing these by hand with a single netmask tool is a daunting task.
Anyone know of such a tool/script?
